What Is the Risk of a “51 Percent Attack” in a Blockchain Network?

A 51 percent attack is a potential vulnerability in a Proof-of-Work (PoW) or Proof-of-Stake (PoS) blockchain where a single entity or group gains control of more than half of the network's total hashing power or staked tokens. This control allows them to disrupt transaction ordering, prevent new transactions from being confirmed, and potentially reverse confirmed transactions, leading to double-spending.
